After a lovely experience at Rainbow’s End, my wife and I decided to head back downhill to try Oldenburg. We were greeted condescendingly asking if we had a reservation. We did not, but since 80% seats were empty, I asked if we could have wine poured without having to hear the story of each wine at any convenient seat. We were told “we don’t do that here, we offer a 1.5 hour experience, you can make a booking for tomorrow”.
If you want a peaceful respectful experience, drive past Oldenburg and visit Rainbow’s End instead.
